Abstract

A method for estimating an electrophysiologic response contained in a measured signal includes obtaining a plurality of samples and defining a plurality of bins, each of which corresponds to a range of values of a sorting parameter associated with each of the samples. Each sample of the measured signal is then classified into one of the bins on the basis of a value of a sorting parameter associated with that sample. Then, for each bin, a statistic indicative of samples classified into that bin is maintained. On the basis of these bin statistics, the desired electrophysiologic response can then be estimated.
